import java.util.*;

public class Solution {
  public static void main(String args[]) {
    Scanner scan = new Scanner(System.in);
    int n = scan.nextInt();
    for (int i = n - 1; i >= 2; i--) {
      //get the maximum cofactor of i and n
      int a = n,
        b = i;
      int rest = a % b;
      while (rest != 0) {
        a = b;
        b = rest;
        rest = a % b;
      }
      if (b == 1) {
        System.out.println(i);
        return;
      }
    }
    System.out.println(1);
  }
}
